ADJUSTABLE SCREW-CONVEYER HANGER.

Specification of Letters Patent.

Patented Sept. 5, 1911 Application led October 1, 1910. Serial No.584,910. l

To all whom it may concern:

Be it known that I, MAURICE H. Eu- MERICH, a citizen of the UnitedStates, residing at La Salle, in the county of Lasalle and State ofIllinois, have invented a new and useful Improvement in an AdjustableScrew-Conveyer Hanger, of which the following is a specification.

This invention relates to certain new and useful improvements inadjustable screw conveyer hangers and couplings, the object being toprovide a hanger which can be adw justed to suit any size conveyercasing, or boxes in order to support the bearing in the proper positionwithin the box.

Another object of my invention, is to provide a novel form of couplingmember in connection with the hanger, whereby the conveyer shaft can beeasily and quickly coupled or uncoupled without disconnecting the drivegear or chain in order to replace a broken shaft, as is the case withcouplers now in use, as in order to replace the broken shaft it isnecessary to disconnect all the hangers in order to allow the shaft tobe moved longitudinally within t-he casing or box.

Another object of my invention is to provide a hanger, which isexceedingly simple and cheap in construction, and one which is verystrong and durable, the hanger arms being so mounted, and connected tothe hanger proper that the journal box will be supported in a very rigidmanner, and at the same time be capable of being adjusted.

Another object of my invention is to provide a coupling which is formedof two sections which are so connected to the coupling shaft that theshaft will be rigidly locked between the coupling members, and at thesame time a bearing is formed by the coupling.

`With these objects in view, the invention consists in the novelfeatures of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specifica-tion: Figure 1 is alongitudinal section through a portion of a conveyer casing or box,showing my improved hanger and coupling arranged therein. Fig. 2 is atransverse section casing being broken away. Fig. 3 is a to-p plan view.Fig. 4L is a side elevation. Fig. 5 is a perspective view of one of thehanger arms. Fig. 6 is a front view of the hanger proper. Fig. 7 is aninverted plan view of the same. Fig. 8 is a longitudinal verticalsection partly in elevation. Fig. 9 is a transverse section'. Fig. 10 isa top plan view of one o-f the coupling sections. Fig. 11 is aperspective view of one of the coupling shafts.

Referring to the drawing, A indicates the upper portion of the conveyercasing or box, B the hanger, C the journal box, D the coupling and E theconveyer shafts, which are provided with the usual spiral F.

The hanger comprises a pair of arms B formed of angle bars, and providedwith depending angle ends B2, provided with slots B3, said arms beingsecured to the casing by bolts slightly spaced apart with their smoothfaces opposite each other, and between which the hanger B4 is mounted,which is provided with transverse bores B5 surrounded by square socketsupon opposite sides, in which the heads of supporting bolts Gr, areadapted to fit which extend thro-ugh the slots of the arms, and arelocked by nuts in such a manner that the hanger B* will be supportedbetween the same in a very rigid manner, and at t-he same time becapable of being adjusted, as by shifting the position of the arms inrespect to the box, the hanger will adjust itself to any size box. Thehanger is provided with a plate portion BG having a wedge shape groove,and provided with slots through which bolts I are adapted to pass forsupporting the journal box C, which is formed of two sections, the uppersection being provided with a wedge shaped tongue adapted to i'it withinthe wedge shaped groove of the hanger B4. It will be seen that by thisconstruction, the box can be easily and quickly removed, and the hangerdetached from the arms in order to allow the conveyer shaft coupling tobe detached, as will be hereinafter fully described.

The coupling D, comprises a sleeve formed of two sections, one sectionbeing provided with recesses, and the other with tongues adapted to fittherein, so as to prevent the sections fro-m moving longitudinally inrespect to each other, and said coupling is provided with a flange whichis adapted to co-act with the j o-urnal box for preventing the same frommoving within the same. The coupling forms a bearing, which is adaptedto revolve within the journal box, and is provided with semi-circulargrooves, and square-recesses adapted'to receive the coupling shafts JandA square heads J Which are locked therein by bolts K extendingtransversely through the section of the sleeves, for locking thesections together, and said bolts are countersunk Within the coupling inorder to form a smooth bearing. The coupling shafts are provided Withtransverse bores, adapted to aline With bores formed in the ends of theconveyer shafts through Which bolts or pins are adapted to pass forlocking the coupling shaft J. in position Within the ends of theconveyer shafts E, in such a manner that the ends of the conveyersections Will be locked together, in such a manner that they can beeasily and quickly connected, or disvao connected.

From the foregoing description, it Will be seen that I have provided aconveyer handle and coupling, Which is especially constructed in orderto allow the conveyer sections to be easily and quickly connected, ordisconnected in such a manner that any one of the sections can bereadily removed in case of one of the sections becoming broken Withoutremoving the adjacent sections.

What Iclaim is l. In a device of the kind described, the' combinationWith a conveyer box, of a pair of larms provided With slotted angle4ends carried by the box, a hanger carrying bolts extending through t-heslots of said arms, a journal box carried by said hanger, and a couplingmounted in said journal box.

2. In a device of the kind described, the combination with a conveyerbox, of an adjustable hanger carried by the box, a journal box carriedby said hanger, and a sectional coupling mounted in said journal box.

8. In a device of thev kind described, the combination With a conveyerbox, of an adjustable hanger mounted in said box, a sectional journalbox carried by said hanger, a sectional -coupling mounted in saidjournal box, said coupling carrying coupling shafts connecting the endsof the conveyer shafts.

4. A device of the kinddescribed comprising a hanger carrying a journalbox coupling mounted in said journal box comprising a sectional sleevehaving faces and provided With recesses, coupling shafts mounted in saidgrooves provided with square heads fitting in said recesses, and boltsextending transversely through said sleeve, and heads.

5. The combination With a conveyer box of a pair. of arms lcarried bysaid box, provided With depending slotted portions, a hanger carryingbolts mounted in said slots, said hanger being provided With a plate atits lower end, a sectional journal box carried by said plate, and acoupling member mounted Within said journal box, said coupling membercomprising a sectional sleeve having means for securing the couplingshafts therein.

6. The combination With the meeting ends of a pair of conveyer shafts,of coupling shafts fixed in the ends of said conveyer shafts providedwith square heads, a sectional coupling member arranged over saidcoupling shafts, bolts extending transversely through said couplingmember and shafts, and an adjustable hanger carrying a journal box forsupporting said coupling member.

7. A coupling for conveyer shafts, comprising a sectional sleeve, eachsection being provided With a groove and a recess, coupling shaftsarranged in said groove having heads seated Within said' recesses, boltsextending transversely through said coupling member and coupling shafts,and an adjustable hanger carrying a journal box adapted to receive saidcoupling member.

8. A conveyer hanger, a hanger comprising a pair of arms having slottedportions, a hanger carrying bolts mounted within said slotted portions,said hanger being provided With a plate at its lower end, a sectionaljournal box carried by said plate, a sectional coupling member mountedin said journal box, said coupling member having means for receiving theends of the coupling shafts of the conveyer shafts.
